How about putting together a Vietnamese-inspired cooking kit for your dad? You could include a cookbook of popular Vietnamese recipes or print out some of his favorite recipes from online. Add some essential Vietnamese ingredients like fish sauce, hoisin sauce, rice noodles, and possibly a mortar and pestle (which are commonly used for making traditional dishes like pho and bun cha). You could also throw in some Vietnamese coffee and a traditional coffee filter so he can make his own Vietnamese iced coffee at home. Finally, consider getting him a gift card to a local Vietnamese restaurant so he can enjoy some authentic dishes without the hassle of cooking.
Or you can get him a star map with the date when he welcomed you in this world.
