The correct answer is;


"Why did you stand up and leave?"


The main verb is the past simple of do therefore the subsequesnt verbs are in the infinitive form (leave V1). 


You could say


"Why did you leave?"


Still past simple because of the main verb (did) the fact the a phrasal verb (stand up) has been added means a follow on/subsequesnt action happened in the past which is why "and" is required.


The main verb "did" tells us the tense, the phrasal verb in its infinitive form gives us the beginning of the extra information.
