Hi Cody,
looks like you're lucky You still have the golden circle. All you need to do is solder the battery to the +/- Pads.
As for the broken pad.. Looking at your picture looks like it's the middle one.
There's a golden circle right underneath the missing pad. All you need to do is add some solder preferably fluxed, and attach a wire which you will be jumping to the middle pad on the battery (Basically connect the golden dot to the middle pad of the battery)
After that just cover it up with some tape and you'll be set.
