Villain in this hand is a tight player about 16 V$IP
What could he possibly raising with here? (especially such a small raise). I figured it was a kicker war.

I would probably find a check on the turn. As played fold to his min-checkraise.

AJ looks likely, a 4 or AK are possible. Fold the turn.

With such a small range of hands though and decent preflop aggression wouldn't he have reraised with AK preflop?

You can't assume that without more knowledge of him, and in any case at full ring a flat call preflop OOP with AK is fine.
