Build your double GP/5, Ruby Sighstone, and then go for those supporty-AP items that Axe mentioned (although not banner of command, dafuq). I really, really like Shard of True Ice if you have a hard-initiator like Malphite, Nocturne, etc that you can toss that active slow onto...plus you get the AoE mana regen AND it keeps acting as a GP/5 item.
Twin Shadows has got to be my favorite item in the game as an AP support..especially so in yoloQ.
