Buy spices and ingredients to bring home
Assuming you've enjoyed the food (and, really, that's a pretty safe assumption), bring back some local ingredients like long pepper, chilies, curry power, and star anise. Just make sure they're dried so you don't have issues with TSA. Or pick up some oyster sauce, fish sauce, and shrimp paste -- they make great gifts and you really can't go wrong with any of them.
