Hi - yes, that is actually easy, vegan as well. Rely on your plant meat substitutes, any of the non dairy milk/cheese subs (rice, soy, oat, almond, flax hemp), use egg whites, and add in very well cooked and pureed beans/lentils.
There are a ton of veggie recipes in Eating for IBS and for many of the non-veggie ones you could easily swap in firm tofu or seitan.
The principle would be the same - soluble fiber foundation, add in as much insoluble fiber - carefully! - as you can, and avoid the triggers. Red meat and dairy are major triggers, so you're already avoiding those. Go low fat, not fat free. Even easier as a veggie.
