If you like chips, you can try making oven chips at home and using other spices instead of salt to season them. You can also make tasty oven chips with other veggies like Brussels sprouts, kale, carrots, etc... There are lots of recipes online.
You can find a few lower sodium teriyaki/soy sauces out there(check the labels, though, for amount, they are still be pretty high) or it is possible to make your own teriyaki or soy sauce substitutei (you can find recipes online). It won't taste quite the same of course. Another option for something like this is to use the lowest sodium variety you can find, and have it as an occasional treat, keeping your sodium very low for the rest of the food you eat that day to compensate and avoid going over your daily allowance.
