Cut the salmon into roughly 1-inch cubes, keeping sizes similar, and place into a medium bowl.
In a separate small 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 well with the marinade and let them sit for no more than 30 minutes to avoid mushy texture.
Arrange the salmon bites in a single layer in the air fryer basket; cook in batches if necessary.
Set the air fryer to 400°F and cook the salmon bites for 7-10 minutes, optionally shaking or turning halfway through; they are done when golden on the outside and reach 145°F internally.
While the salmon cooks, mix together mayonnaise, sweet chili sauce, sriracha, honey, and rice vinegar to make the bang bang sauce, adjusting spice to preference.
After cooking, allow salmon to rest for 3-5 minutes before drizzling with the bang bang sauce and serving.
