http://eqrecipes.free.fr/ - You must learn 1005 of 1139 recipes to reach 350 Smithing
You're unlikely to reach that exact point but that's the effective starting point of every book scribed with 300 Smithing, you could for instance reach that point by making Tungsten Chain Bracer Template to go from 0-300, most likely you will learn a dozen or so recipes at least. The most important early recipe is Forged Velium Shuriken, the only recipe you learn while making an Apprentice Smith Trophy but you might prefer making a higher version of the trophy or most likely because you have a 15% Smithing mod item might not ever make a trophy.
The largest point of divergence is whether or not you're willing to make 78 Conflagrant items (63 pieces of armor, 2 armor sub-combines and 13 weapons), if you want to make no or few Conflagrant items you will remove most of your flexibility.
At low levels you have the following farming options to skill up Smithing or to profit from people who do, suggested zone listed, some items drop in many zones, eqtraders and zam are excellent resources for additional information:
14 Flame Agate: random drop from low level mobs that most probably assume is used in JC and is vendor sold and it's neither of those things. It takes a minimum of 56 to learn all the Forged Firebrand weapon recipes.
73 Acrylia: Acrylia Caverns, only non-vendor item for Acrylia (Small/Large) Plate/Chain items, Steel Alloy Rod and also used in 14 Combine Acrylia weapons
14 Brick of Black Acrylia: Grimling Forest also requires Essence of Darkness and Akheva Blood from Maiden's Eye to make Black Acrylia weapons
14 Windstone and Essence of Wind: Twilight Sea along with Acrylia for Combine Acrylia weapons
3 Chunk of Condensed Flame, Ice and Shadow: various Luclin zones including those, for Smithing each makes an Arrowhead
12 Velium: Velious, best option changes as you level, keep in mind that you can crush Velium weapons, Forged Velium weapons, Enchanted Velium Bits and Spool
72 Rujark LDoN: Goblin Bones/Bone Temper for Calcified (Small/Large) Steel/Ring items
72 Guk LDoN: Pondweed/Swamp Temper for Deep Cavern (Small/Large) Steel/Ring items
72 Miragul LDoN: Ice Lichen/Lichen Temper for Frosted (Small/Large) Steel/Ring items
72 Mistmoore LDoN: Gargoyle Granite/Granite Temper for Gothic (Small/Large) Steel/Ring items
72 Takish LDoN: Sand Verbena/Sand Temper for Sandblasted (Small/Large) Steel/Ring items
- Miragul LDoN is also one of the sources for Permafrost Crystals/Permafrost Extract/Blue Dye but base Permafrost is likely best
- Guk LDoN is also one of the sources for Sarcoscypha Fungus/Sarcoscypha Extract/Red Dye but ground spawns in Lesser Faydark are likely best
16 Undifferentiated Ore: Cobalt, Fulginate, Indium, Iridium, Iron, Osmium, Palladium, Rhenium, Rubicite, Silvril, Tantalum, Thalium, Tin, Titanium, Tungsten, Vanadium
14 Dyes and Undif Ore are used to make Violet Hero's Forge Plate/Chain Ornaments
22 Sunshard Dust: for Smithing is only dropped component for 7 Crude Energeiac Plate, 7 Worked Energeiac Chain and 8 Dull Energeiac weapons
22 Sunshard Pebble: for Smithing is only dropped component for 7 Tempered Energeiac Plate, 7 Beaten Energeiac Chain and 8 Shining Energeiac weapons
22 Sunshard Ore: for Smithing is only dropped component for 7 Polished Energeiac Plate, 7 Linked Energeiac Chain and 8 Shining Energeiac weapons

This leaves 206 recipes and you need to learn 72 of these recipes if you learned every Conflag recipe to 150 if you didn't learn any:
If you are a Karana Worshipper you get 4: Steel Arrowheads, Arrowshafts, Fletch and Working Knife
If you raid in RoS you probably get 1: Combine Enamel Kit
If you do the Shawl you get 1: Brell's Heart Silver Filigree
If you do EoK quest Methods of Sarnak Destruction you get 1: Mana of the Sarnak Compressor
If you do Earring of Solstice you get 1: Mistletoe Cutting Sickle
The remaining oddballs:
3 Battle Cam Parts: quite possibly easy recipes, but I didn't check out Devastation to find out
Drunder's Steel: requires Decorin Ore Shard off an add from Tagrin Maldric in PoTactics, may be easy to obtain, I didn't check it out
Last Blood Seal (Last Blood Steel): rare drop from a place (DSK) you likely have little reason to visit
Poxysmit's Hole Punch: requires Scrindite's Senescent Scribbles from Belfast in Corathus, seems like too much bother for 1 recipe
30 recipes require Bazu Blood, it's a reasonably common drop, I couldn't figure out a place that Bazu were common, going by Zam there are no Bazu in the Precipice of War mission, maybe there is a good spot in Korafax
You could at least pick at the recipes, assuming no failures for 1 Bazu Blood and 1 Pyrilen Flame you get 2 recipes. 4 of each for 2 recipes might not seem like a good idea even if 1 of each does
30 recipes: Vah Shir Smithing from Master Barkhem in Shar Vhal, leads to Bloodling Plate and Humming Orb related recipes, could be quick, I didn't check it out
10 recipes require Lightning Core(s), it's about a 1 in 250 drop from Lightning Warriors in MPG, if you get any while looting Magnetized items or Epic Orbs you can make a recipe or sell it
7 Tae Ew Chain: this should actually be in the easy recipes but I decided to group all Tae Ew together, takes 14 Tae Ew Blood Vials with no failures
7 Tae Ew Plate: 32 Pristine Tae Ew Scales, 7 each Tae Ew Blood Vial, Froglok Blood, Iksar Blood and Sarnak Blood if no failures, I got the Chain done and had 1 Pristine Scale and didn't go back to Cazic Thule
4 Tae Ew Dagger, Longsword, Shield, Two Hand Sword: 1 of each Blood per item
2 Tae Ew Mace, Two Hand Hammer: 1 of each Blood and Swampwood Stave
The rest is PoP, if you're also going to do Brewing which requires all but 19 recipes you are most likely going to make the 6 Tempers so do that now and have 1 shot at each Sheet (makes 2) for Plate armor:
Sheet of E'cian Ice (PoWater): Povarian Mist Temper which is Shimmering Fish Gills (Sharks), Soapstone Powder (Hraqui) and Water Mephit Blood (Triloun)
Sheet of Electrified Copper (BoT/Storms): Hurricane Temper which is Drop of Pure Rain (BoT Water), Powdered Sandstorm Pearl (BoT Fire), Storm Rider Blood
- this is the only PoP ore you will ever specifically farm, every other Ore you have way more than you will ever need just by looting Temper ingredients, Rain is the bottleneck
Sheet of Immaculate Steel (PoEarth): Liquid Stone Temper which is Earth Mephit Blood, Liquefied Earth (Mudwalker event and near it), Powdered Granite (Peregrin event and near it)
Sheet of Molten Ore (PoFire): Liquid Inferno Temper which is Fire Mephit Blood, Metallic Substance (common), Powdered Magma Crystals (Fire Elementals)
- probably the easiest zone just because of the volume of mobs assuming you are high enough level that repop is an issue in other zones
Sheet of Nightmare Iron (PoN): Night Terror Temper which is Fetid Slime (Slarghilug), Nightmare Mephit Blood, Powdered Midnight Stone (Caves)
- Midnight Stones are rare which is only somewhat offset by the large volume of mobs in the caves
Sheet of Wind Metal (PoAir): Flowing Rainbow Temper which is Air Mephit Blood, Gaseous Condensate, Powdered Fog (last two from Air Elementals)
6 Rings (Scales for PoWater) same Temper also makes 2 for Chain armor
6 Studs same Temper and also makes 2 for Leather armor (Tailoring)
84 pieces of PoP Armor, Wrists indirectly require a total of 1.5 Tempers, 2.5 each for BP and Legs, 2 for each of the other slots, everything except Temper is really trivial
Leather (Tailoring) requires 1 Temper for Wrist, 1.5 each for Hat and Arms, 2 each for Boots, Gloves and Legs and 2.5 for BP.
Cloth (Tailoring) is a separate Temper and 1 for each piece:
PoWater: Waterweave Curing Agent: Slarghilug Slime(3) (Hraqui) overlap
BoT/Storms: Stormweave Curing Agent: Storm Ent Sap(3) (Storms Trees) don't or rarely drop Bricks
PoEarth: Earthweave Curing Agent: Stonewood Sap(3) (Trees) no cluster of them so try to mix some in while killing other mob types
PoFire: Firestrand Curing Agent: Obsidianwood Sap(3) (Spiders) overlap
PoN: Night Terror Curing Agent: Nightmarewood Sap(3) (Trees) so rare it's impractical to even obtain the Brewing recipe
PoAir: Airstrand Curing Agent: Featherwood Sap(3) (Spiders) quite annoying, it's possible that failing the Ring Event would repop them faster but I didn't try
