Am I playing like a huge LAG fish this hand?

[Spaded]

Villain has VPIP of 62%, PFR of 30%, showing very aggressive tendencies postflop after 90 hands. This whole session i was playing tight, maybe even weak-tight 15%VPIP (no cards!) 5%PFR, but that probably doesnt matter since players at $25NL 6max don't think often.

Villain had to think a long time before calling, but finally called it down. Should I have made a small raise on the flop? Should i have even called the prefop miniraise with a suited 1-gapper? Should i not have put nim to a decision for a significant part of his stack with my flush, straight, and full house draw?
