Get a better jungler/support. Other than that, idk. I haven't fought him much.

Dude, I'm instakilled. I can't even flash that fast.
Blame your Blitzcrank. Or buy a pink or sweeper...
Its not instant. He screams and warns you when he presses his R and you are also able to see 2 glowing eyes on top of your head so you have plenty of time to hugg your Leona, Braum or whoever as Rengar has ZERO chances to kill you if CCed after his jump unless he bursts empowered W which will cost him tons of damage. If you got cought alone sonewhere, that's whar Rengar is supposed to do.
Positioning
Don't let him get free stacks and his damage becomes really lackluster in the mid game
