You need armor pen on Vayne, either LW or BC. LW is ideal because of the Q & E deal burst which scales with AD. Black Cleaver is good but you don't get the full benefit until after the 3rd hit so if you open with a Q -> E combo, you aren't getting full penetration. As a general rules BC is better DPS against targets with less than 150 armor, and LW is better agaisnt target with more than that.

However as another poster said, when you get that late into a game replace your boots with another phantom dancer or a trinity force, and max out on elixirs. Also if you have all that and are really flush with cash, sell your GA when the resurect timer is down and buy some other defense item like Randuins, keeping note of the timer. The GA timer still ticks if you don't have the item, but obviously when the passive is on cool down you aren't getting as much benefit from it as another D item like Randuins. You can always buy it back after the cool down comes back.
