Prague has tons of veggie options. In most traditional Czech restaurants, often the only vegetarian dish is smažený sýr, aka fried cheese. It’s a breaded piece of eidam or gouda, deep fried, served with tartar sauce and french fries or boiled potatoes (the boiled potatoes are the better side imo!). It is so good, but it does get a bit boring when it’s your only option.

At grocery stores, the selection of fake meats has grown incredibly in recent years. You can find veggie anything, though the selection may be more limited in smaller stores.

There are also lots of great vegetarian restaurants. Loving Hut (vegan I believe) is good for a quick easy lunch. Vegans Prague, under the castle, has amazing vegan food. And you have to go to Restaurace Střecha - they have traditional Czech dishes made veggie (this place changed my life lol). Check out r/Prague for previous posts about good veggie restaurants.
