The Ramen place (SLR.!) in Yas mall has vegan options (just ask the staff). As did the Wonton place, I think. Also, as you enter the mall from the shuttle bus drop off, there's a Lebanese place upstairs, which should have standard vegan options, such as falafel, houmous, tabouleh, fatoush. Can't remember their menu, but you could always ask about yakhnet (aubergine) dishes that are normally made with a tomato sauce, no dairy or butter. Just remember to ask for plain rice, as Lebanese rice can often have butter drizzle over it. Immediately outside the hotel pool area, through the gate to the waterfront, there's an ice cream (popsicle) shop of you turn right (first shop). They have some vegan pops. The hotel breakfast buffet has plenty of options, and if you talk to the chefs at each station, they'll be able to advise. Always best to double-check, although their allergen signage seemed to be accurate. We had mostly the Indian breakfasts (idli and sambar / masala dosa), but the Arabic selection had some great flavours as well. Also along the waterfront, outside the hotel's pool gate, there's a place called Central, that does a vegan burger (passable, rather than exquisite). There's a few options there, but many staff seem to be fairly up to speed with veganism, and you shouldn't have any problems (unless you encounter someone where you don't share much common language - English might be a third or fourth or more language for many of the hospitality staff).

Yes…all room types get free access to the them parks and free shuttle buses to get you there
