Combine the seasonings (cumin through cardamom) in a small bowl. Stir them into the yogurt; add the lemon juice and stir to combine. Place the fish fillets in the mixture; cover and refrigerate for at least 30 minutes and no more than 24 hours.
Heat the olive oil in a large skillet. Drain the fish and saute in the skillet over medium-high heat, turning once, until it flakes easily with a fork.
