Combine first 5 ingredients in a zip-top plastic bag; seal and shake vigorously. Add scallops; seal and marinate in refrigerator for 20 minutes. Remove scallops from bag, reserving marinade. Thread 4 scallops, 2 figs, and 2 lemon quarters alternately onto each of 4 (12-inch) skewers.
Coat a grill rack with oil. Place kebabs on grill rack; cook 6 minutes or until scallops are done, turning and basting with reserved marinade.
