Raise more preflop - i ilke at least 4 BBs + 1 BB per extra player, and even more at a loose table or when out of position like in this hand. You are trying to reduce the players in the hand, ideally you want to be heads up, and your preflop raise only managed to get 1 person to fold.
As played, I lead the flop for a pot sized bet and fold to a raise. If called I re-evaluate on the turn, and probably check/fold to a decent turn bet.
