Preheat the air fryer to 400°F for 3 minutes and arrange a wire rack nearby.
Pat chicken tenderloins dry with paper towels; toss with lemon juice and ½ teaspoon kosher salt and let sit 5 minutes.
Combine flour with ¼ teaspoon salt and garlic powder in one shallow bowl, whisk yogurt and lemon zest in second bowl, and mix panko with cracked black pepper in third bowl.
Dredge tenders in flour, dip into yogurt mixture, press into panko, then repeat yogurt + panko for a double coat; press crumbs firmly to adhere.
Arrange tenders single-layer in air fryer basket, spray lightly with olive oil, and cook at 400°F for 8–10 minutes, flipping halfway, until crust is golden and internal temp reaches 165°F.
Transfer to wire rack to rest 3 minutes; serve with lemon wedges and chosen dip.
