How to start being vegan?

At the moment im a pescatarian but im thinking of slowly going full vegan eventually so im just wondering how can i do it and how to replace certain foods. Im a student so i dont have a really big budget and i still want to eat foods that are nutritious and healthy. also sometimes i eat foods my mom makes as well which arent vegan so besides those id want a full vegan diet. One product i want to replace the most is eggs, i want a food that can be cooked just as easily and taste decent. thank you!
