this is not a scary board for his hand, which is probably 1010+ I would reraise to $16 and hope he pushes on the flop.

As played, the call of his reraise is not bad because it can make him seem like he has control if not reraised, but if you do this, make your goal to get all the money in on the Turn. I think you lead turn with like a 1/2 pot bet, expecting him to come over the top.
