AWESOME!, Ive been veg since I was 12, despite the namecalling and scrutiny from everyone i know. Now that i cook all the time people no longer scrutinize, they eat my morally sound,healthier food and dont complain. lol. I dont really go by books but i do have three in my collection that i love. One is "vegan with a vengeance"- although i am vegetarian , not vegan i do eat vegan dishes on occasion, or i will sub some of the ingredients in this book for eggs, cheese or real milk. "veganomicon"- which is linked to the first one mentioned.. and 'Lord krishnas cuisine, the art of indian vegetarian cooking" i love indian food, and the hare krishnas take their food seriously because they offer everything they make to their God. The food is perfect, savory sauces, confections, just like royalty.
Most of the time i dont use a cookbook, i was raised eating meat so i go for a combination of food i taught myself how to make, like indian, mediteranean, chinese, japanese , thai, mexican,italian, you name it, i either omit the meat you would normally see, or replace it with mushroom, cheese, or mock meat (either tofu, or seiten, or gluten) I make my own recipe of mock meat using wheat gluten and peanut butter and water, i bake it, then i crumble it up and fry it in a pan with olive oil and spices. it replaces hamburger style for chili, tacos, burritos, sloppy joes, chilis, etc... You can buy T.V.P. (textured vegetable protein) and soak it, spice it up, and add it to anything. Tofu is nice too, but prepare it according to strict directions, it can be quite bland.
But when i dont invent, or learn my own style i eat very basic american food, only meatless. In most cities you can find, sliced mock meat of all varieties, mock bacon, chicken nuggets, riblets, a thousand diff varieties of veggie burgers, chik patties, sausage, sliced, linked, small or large, hot dogs,stuffed bisquits, enchildas, premade stuff. Its all available at kroger, trader joes, whole foods, central market, randalls, h.e.b., Ive never been in a mainstream grocery store that didnt at least have something mock meat wise.
Good luck, hope this helps and congrats on the best thing you can do for your families diet!!
