How to beat Thresh as Janna: the early game

Level 1 is yours — before he has Flay, Thresh's lone Q hook is easy to dodge and you can chip with Zephyr; but from level 2 his hook-plus-Flay lockdown lets him threaten every all-in and win the trades. Level one is yours before the chain has a follow-up, so chip him and push while it lasts. After that, hold the tornado for the hook and interrupt the approach rather than answering it. Shield your carry the moment the chain is airborne, and keep the wave between you.
