Prep & season: Pat salmon dry. In a bowl, combine chipotle, smoked paprika, garlic powder, salt, and almond flour. Add salmon; mist lightly with oil spray and gently toss until every cube is coated.
Preheat the fryer: Heat air fryer to 400°F for 5 min.
Air-fry: Arrange salmon cubes in a single layer. Air-fry 6–8 min, shaking halfway, until exterior is deep golden and internal temp hits 130–135°F for medium.
Finish & serve: Squeeze with lime, scatter cilantro, and serve hot with chipotle-lime mayo or over cauliflower rice.
