Cook the basmati rice in simmering water for 12 minutes or until tender. Drain well. Meanwhile, preheat the broiler to medium-high. In a bowl, mix together 4 tablespoons plain yogurt with 2 tablespoons tandoori curry paste. Add the shrimp and toss to coat. Tip onto a foil-lined baking tray, along with the marinade, and broil for 4-5 minutes or until just cooked through.
