I never bother with bought sauces.

Honey Soy : ginger, garlic, sesame oil, honey, soy.

Thai-ish Ginger, Lime & Soy: sesame oil, lots of ginger, garlic, soy, lime (or lemon) juice, and finish with sliced spring onions and chopped coriander. I also use finely shredded kaffir lime leaves which just make it absolutely awesome, but we have a tree so that's easy for us. Otherwise I probably wouldn't bother. Lemongrass would also be good, as it helps the sweet/sour/salty blend. I don't use fish sauce but you could if you wanted. I do this with green vegies and rice stick noodles but you could use whatever vegies you want and serve it with rice instead.
