I thought of doing one of these but know what the general reaction to veganism is here so wasn’t up for the comments!
Have a few questions 
How long have you been vegan?
Are those you live with vegan?
What made you go vegan (i.e. documentary, veganuary, book, conversation)?
What’s your favourite recipe?
Is your city/ town vegan friendly?
Do you do any advocacy for animals? Is it something you’re considering?
Do you take vitamin B12 and D, iodine and omega 3 or just use fortified products/ seeds?
Has your health improved since making the change?
