Keep folding until you get a good hand. Once in a while, with decent hands, try to steal some blinds if only one-two players called.
But the main idea in this situation is : be patient. As you said, you have a good stack of chips, which allows you to scan for the best hand to take action with.
P.S: also, while folding, study the opponents. Some will try to take advantage of you if they notice you keep folding, and this way they can make you drop a decent hand even if you own their hand : this also can help you get "hot" again 😉
