[Doctor Who] Prior to the time war what did day to day life on Gallifrey look like?

How many time lords were there? What did they do for fun? How did their economy function? And so on.

The problem with your question is that there really is no "prior," as a direct result of the Time War itself. 

When you have two time traveling empires at war with one another, the concept of time itself breaks down. The combatants keep using more and more aggressive time incursions to try to disrupt each other's existence. Eventually, you have to militarize your entire civilization's past, so as to prevent the enemy from erasing your creation, or rewriting it such that you are always will have been their slaves (language tense of course is a problem, here). 

Individual Time Lords and Ladies may have memories of childhoods in glorious cities, among beautiful natural wonders. These are the lucky ones who had their timelines protected behind walls of ontology that weren't horrible. Others might recall being raised in an infinite battlefield of nightmares, or spending their entire lives in a TARDIS at battle stations. 

The Time War threatened to not only expand this terrible state of affairs to all sentient life in the universe, but to absolutely destroy all concept of continuity, everywhere and everywhen. That is why we are all better off that it was time locked away, although strangely enough history does not record just who might have done such a thing.
