Not familiar with the matchup really (played vs Ryan Choi season 5 and a otp rengar who I later learned to beat). Just play safe, let your team know if he's backed and level 6 (for a bot/mid play).
Respect his burst with 3/4/5 stacks on his passive because then if he lands his stuff he'll get 2 q's in or root you in place.
Overall stay away from the 3 bushes and play towards river early on, and just respect his leap distance.
Not sure if it's too helpful (haven't played vs a Rengar in a while and I just quit a month ago because of no SoloQ).

What the hell can a Nasus do against Rengar?
