Cut salmon fillet into uniform 1-inch cubes. In a medium bowl, toss salmon with olive oil, honey, soy sauce, smoked paprika, garlic powder, salt, and pepper until evenly coated.
Preheat air fryer to 400°F for 3 minutes. Arrange salmon bites in a single layer in the air fryer basket without touching. Cook in batches if needed.
Air fry for 5 to 7 minutes until salmon is cooked through, crispy on edges, and reaches 145°F internal temperature.
While salmon cooks, whisk together Greek yogurt, sweet chili sauce, and sriracha to make bang bang sauce.
Let salmon rest for 3 to 5 minutes. Drizzle with bang bang sauce and garnish with green onions and sesame seeds. Serve immediately.
