Preheat the air fryer to 400°F (200°C). Pat the salmon fillets dry with paper towels.
In a small bowl, mix olive oil, chili powder, garlic powder, smoked paprika, and salt. Brush the mixture over the salmon fillets.
Place the salmon fillets in the air fryer basket in a single layer. Cook for 8-10 minutes, or until the salmon is cooked through and flakes easily with a fork.
While the salmon cooks, prepare the slaw by combining shredded cabbage, cilantro, Greek yogurt, and lime juice in a bowl. Toss until well mixed.
Warm the corn tortillas in a dry skillet or microwave. Flake the cooked salmon into large pieces.
Assemble the tacos by dividing the salmon and slaw among the tortillas. Serve immediately.
