When leaning against Vayne, a highly mobile ADC with strong single-target damage and kite potential, both Jax and Kennen have unique approaches and strategies to counter her throughout the different stages of the game.

Jax vs. Vayne
Early Game:

Laning Phase: In the early game, Jax should focus on farming and trading effectively. Use Leap Strike (Q) to close the gap and Empower (W) for burst damage. Utilize Counter-Strike (E) to dodge Vayne’s auto-attacks and Condemn (E), which can negate her trading potential.
Trades: Engage with Q and follow up with W for a quick burst. Use E defensively to avoid taking too much damage from Vayne’s Silver Bolts. Aim to trade when Vayne's Tumble (Q) is on cooldown to limit her mobility.
Mid Game:

Roaming: Jax’s mid-game strength lies in his ability to roam and split-push. After pushing the wave, look for opportunities to help other lanes or secure objectives.
Dueling: With items like Divine Sunderer and Blade of the Ruined King, Jax becomes a formidable duelist. Use Grandmaster’s Might (R) to gain resistance and additional damage during extended trades. Be mindful of Vayne’s Final Hour (R) and her increased mobility and invisibility.

Team Fight Strategy:

Execution: Engage with Q onto Vayne or other squishy targets. Use E to dodge key abilities and stuns, then follow up with W and R for maximum damage and survivability.
Positioning: Stay on the edges of fights, looking for opportunities to dive onto Vayne or other high-priority targets.

Kennen vs. Vayne
Early Game:

Laning Phase: Kennen’s early game against Vayne focuses on poking and farming safely. Use Thundering Shuriken (Q) to harass Vayne from a distance and Electrical Surge (W) for consistent poke. Utilize Lightning Rush (E) to reposition and avoid Vayne’s Condemn (E).
Trades: Engage in trades when you can land Q and follow up with W. Use E to escape if Vayne engages aggressively. Focus on poking her down before committing to an all-in.
Mid Game:

Skirmishes: Position yourself to hit multiple enemies with R. Use E to get into the middle of the fight and Zhonya’s Hourglass to stay safe while dealing damage.
