In the right team comp, if you can get auto attacks in, I've found that building Nashor's Tooth (and sometimes Lich Bane) on AP Kog can add a LOT of damage. His W already adds so much % max health damage on hit, it would be a shame not to take advantage of his autos. The build looks like this:

Tear -> Luden's -> Sorc Shoes -> Liandry's -> Nashor's -> Void Staff -> finish Seraph's or trade in for Lich Bane.

The idea is that other than Kog's E, his AP ratios are pretty mediocre, so Magic Pen and on- hit can be more beneficial. Luden's and Lich Bane also give Kog some nice bonus Move Speed, which is really nice for him.
