In a small bowl, whisk together the mayonnaise, Thai sweet chili sauce, sriracha sauce, honey, and lime juice until well combined. Set aside.
In a large bowl, combine the salmon bites with olive oil, garlic powder, onion powder, smoked paprika, salt, black pepper, and cayenne pepper if using. Toss until evenly coated.
Preheat your air fryer to 400°F (200°C) for about 3 minutes.
Place the seasoned salmon bites in the air fryer basket in a single layer. Air fry for 8-10 minutes, shaking the basket halfway through.
Transfer the cooked salmon bites to a serving platter and drizzle with the prepared Bang Bang sauce. Serve any remaining sauce on the side.
