It is your choice, but make sure you dont neglect your mineral and vitamin sources. If you aee going vegan,eat some dates, dark chocalate, a variety of fruit to get your essential vitamins and minerals. Drink plenty of coconut water. I personally dont reccomend those "healthy vegan milk" alternatives, its nonsense.
Just a note, I am not a vegan and I do not support their ideology, i am just a dabbler. I like to eat new stuff so I occasionally switch up my diet.
For your source of protien you can eat lentils, beans, and other stuff (my knowledge in this area is shallow)
But dont neglect the vitamins,minerals and protien sources. Theyre really important.
