How do I bake chocolate chip cookies like Subway?
It would help if you could supply a complete list of ingredients (including the type of flour you used) and the temperature you are using to bake your cookies and even what shelf in the oven you are baking on.  Were the cookies wrinkled when they came out of the oven or did they wrinkle as they cooled?

A lot of different factors determine how CCC's behave in the oven.  Wrinkly cookies usually mean that the cookies expanded during their bake time then contracted either inside or outside of the oven.  What causes that behavior could involve how much fat is in your cookie dough or how much egg white vs. egg yolk you used or how much leavening you use (more leavening doesn't necessarily mean more rise - sometimes if you have too much leavening your cookies can over-expand then collapse leaving a wrinkly top).  There are other possibilities, but it's hard to make a useful recommendation without knowing the rest of your cookie equation.
