Mince garlic and onion, mix with salt, pepper, and all the ingredients other than the leeks, flour, and tempeh, with mortar and pestle/food processor if you have them

Mix the spices into the flour mixture, add chopped leeks. Add water until the batter is runny but doesn't drip if you try dropping it from your spoon.

Heat the oil on your wok, check whether they are hot enough by dropping some batter and they bubble.

Coat tempeh slices with the batter, ensure that each slice has enough leeks on both sides, fry until yellow brown.

Eat as snacks or with steamed rice, wide a side of soy sauce or you can try my way I guess (with some cheese but definitely far from traditional)
