What do you put him on? Was i correct in leading the turn? Should I have raised more/less preflop?

After the turn raise, I think you are beat. AA/KK/QQ/TT/88/KQ J9-spades, A9-spades. T8suited (not spades)... probably NOT KTs but that's about all I'll rule out.

The only hand you beat is AQ/QJ, and if it's spades he still has outs.

With out a read that he is making a semi-bluff into strength here, I have to fold. Note the less than all-in raise too.

Raise more pre-flop.

Hero has an easy fold to the turn c/r. If you suspect his line here is to c/r and/or will stab at rivers, then I like checking. Against typical loose/passives then the turn is an easy bet/fold.

obvious fold on the turn. My best guess would be AJs spades, I'd think he'd probably raise the turn more with a set.
