Preheat the air fryer to 400°F (200°C).
Cut the salmon into bite-sized pieces.
In a bowl, combine the mayonnaise, sweet chili sauce, sriracha, garlic powder, and lime juice to create the Bang Bang sauce.
Toss the salmon pieces in the sauce until fully coated.
Dredge each piece of coated salmon in panko breadcrumbs until fully covered.
Arrange the salmon bites in a single layer in the air fryer basket.
Air fry for 10-12 minutes, or until golden brown.
Serve warm with the remaining Bang Bang sauce for dipping.
