Cut the salmon into roughly 1-inch cubes, aiming for evenly sized pieces, and place them in a bowl.
Whisk together olive oil, lemon juice, honey, soy sauce, minced garlic, onion powder, smoked paprika, pepper, and sea salt to create the marinade.
Coat the salmon pieces thoroughly in the marinade and let them rest for up to 30 minutes, avoiding longer to prevent mushy texture.
Arrange the salmon bites in a single layer inside the air fryer basket; work in batches if needed to avoid overcrowding.
Set the air fryer to 400°F and cook the salmon bites for about 7 to 10 minutes, optionally shaking or turning once midway.
Meanwhile, blend mayonnaise, sweet chili sauce, sriracha, honey, and rice vinegar in a bowl to prepare the bang bang sauce, adjusting spiciness to your liking.
Once cooked, let the salmon rest for 3 to 5 minutes, then serve topped with the bang bang sauce and enjoy!
