Preheat broiler, with rack in upper third of oven. Place couscous in a large heat-proof bowl. Cover with 1 1/2 cups boiling water, then place a plate over top of the bowl. Let stand 15 minutes, then fluff couscous with a fork.
Meanwhile, combine garlic, cumin, paprika, coriander, lemon zest and 2 tablespoons olive oil in a mortar and use pestle to smash ingredients together to form a paste. Season generously with salt and pepper. Rub cut sides of eggplant with spice mixture and transfer to a broiler-proof baking dish. Broil 15 minutes, or until eggplant are tender and charred.
While eggplant broils, chop cilantro and almonds and transfer to a bowl. Stir in 2 tablespoons oil, lemon juice and remaining 1/4 teaspoon paprika; season with salt and pepper. Serve eggplant with couscous, topped with a dollop of yogurt and a spoonful of salsa.
