It sounds like you're essentially looking for Ratio by Michael Ruhlman. It has plenty of what you call master recipes - ratios of ingredients for various recipes. It's not just baked goods - also batters, stocks, meats, sauces, and custards. And it doesn't stop with the ratios; there's a lot of additional discussion of actual recipes to make on top of the plain base, as well as discussion of how varying the ratio will affect the result.
There are of course plenty of reviews on Amazon and elsewhere online, but if you like perspective from members of this site, yossarian also reviewed it in a blog post a while back. I also own it and think it's pretty great.
There's also an app based on the book for Android and iOS (thanks, Stefano). I haven't tried it but it looks like the reviews are mixed to positive - not the shiniest app but it does contain a lot of the basic information.

These are the things that popped up in my mind at first glance:
Volume
How bigger the thing, how longer it will take to be fully baked. This is the reason why you find such a difference in the baking times for banana bread and banana muffins.
Surface Area
The volume can be the same (ground surface x height), but the surface exposed to the heat can differ. If something is flatter, the center is more rapidly reached. If you would bake your bread in a normal bread mold, it would take a longer time than if you would flatten out a bread on a baking sheet (but note that the volume is the same).
Oven temperature
Something very obvious. If it's hotter, it won't have to bake as long. However, don't play too much with this. I would advice to use the temperature a recipe has recommended. If you put it too hot, the outer parts can burn, when the inner parts would not be baked fully. This question is related.
Vessel Material
Some materials conduct heat better than others. As a consequence, some things will be faster done in metal than in glass for example. (But I believe this has a less important role than the other factors I've mentioned. I can't say much about it, since I don't know a lot about it.)
