In a medium bowl, stir together yogurt, garlic, ginger, cumin, coriander, turmeric and salt until combined.
Place the salmon fillets in a large baking dish, lightly coated with cooking spray. Spoon half of the yogurt mixture over the salmon and, using your hands, rub it all of the salmon. Cover with plastic wrap and let marinate for at least 4 hours, and up to overnight.
Preheat oven to 375 degrees F. Remove the plastic wrap and cover the baking dish with foil. Bake for 7 minutes. Remove foil and bake for additional 5 to 7 minutes, or until salmon is just cooked through.
Serve the salmon with the remaining sauce, if desired.
