if your doubling the WHOLE entire recipe then yes you need to triple the yeast as well, unless you want a slower rise, but if you want it to perform the same way just simply triple the amount. In the process of doing all this, do yourself a favor and right everything down in the amount thats doubled or tripled, it'll make your life a whole lot easier in the long run.
Breads without spices scale smoothly. When we were running a bakery, we put our formulas into spreadsheets and scaled from as few as 2 loaves to as many as 50 without changing the proportions of anything. I never felt that it was necessary to use proprotionally more, or less, riser as the recipe was scaled up or down.
If the recipe is doubled, double everything. If the recipe is tripled, triple everything.
One consideration if you are baking at home - how many loaves can you bake at a time? Fully risen dough can only be held so long and then it starts to deteriorate. With wheat breads, I wouldn't make more than two oven loads at a time. If it's all the same recipe, I'd wait a bake time between batches.
So, if you need to make 6 loaves and can bake 3 at a time, I'd make all 6 at once. Usually wheat breads can be held a bake cycle. If I needed to make 9, I'd make 3, wait however long the bread would bake, and then start a batch of 6.
