Preheat a 6-quart air fryer to 390°F for 3 minutes. Put flour in a shallow dish, egg beaten with water in another, and panko mixed with sesame seeds, salt, and garlic powder in a third.
Lightly flour tenders; dip in egg and press into crumbs. Dab surfaces with measured oil, divided between batches.
Arrange half without overlap. Air fry 5 minutes; turn and cook 5 to 7 minutes more until golden and at least 165°F.
Transfer to rack; repeat remaining tenders. Mix Dijon, honey, and yogurt for dipping.
Rest final batch 3 minutes; serve with honey-mustard dip.
