It isn't easy-and can be very boring.
It's not possible to go AS low carb as someone omnivorous.
My go-to meals are;
Salad with either a faux-meat or tofu component, seeds, avocado, olives, olive oil or vegan mayo as dressing
Low-carb wraps with a variation of the above inserted, or vegan sausages and fried red onions, bit of salad
Celariac chips make a good side-dish as does coleslaw made without carrot.
Popadums (5carbs each) dipped into guac or salsa make a good snack.
A version of this;

Spaghetti bolognese made with vegan mince and Shirataki noodles
Vegetable curries with shirataki rice.
I think there are some others but that's what springs to mind for now.
I do have some days off-I'd get VERY bored otherwise.
