Laning Yi is not viable. The only viable AD Yi is jungle Yi.
Start Cloth 5 HP Pots or Vamp Scepter.
Zeal > Phantom Dancer
Quicksilver Sash/Warmogs Armour
Guardian Angel/Atmas Impaler
Wriggles > Bloodthirster (Optional)
You are level 16, so building full damage may work well at your level. Once you reach level 30, you will find that Yi is an awful laner because of his lack of sustain, very weak early game and lack of burst damage. Never EVER build more than a single Phantom Dancer, Bloodthirster or any other damage item on Yi, because he has many natural offense mechanisms but no defensive ones, therefore you must build to your weaknesses. Do not listen to people who give you a glass cannon build and say that lifesteal will keep you alive in a team fight and will allow Yi to be unbeatable 1v1, because the game is not about 1v1, and even if it was, Jax would easily destroy Master Yi in two hits because Jax is a better duelist than Master Yi.
Quicksilver Sash provides good magic resist, and the active allows you to escape CC which is Master Yi's biggest weakness. Guardian Angel gives armour and magic resist plus a revive so even if you do get focused in a team fight, you can come back to life and continue fighting. The Atmogs combo allows you to become tanky while giving AD and crit.
