Simply download and re-install the OS. This will not cause any data or settings loss and will automatically create a fresh recovery partition.  You should be able to download the current OS from the App store for free.

Which versions of the OS is it?  Do you have the full installer on the USB drive? Is the USB drive bootable?

Having the OSX Installer on USB drive will not boot, you need to follow one of three methods to create a bootable USB OSX installer, or a harddrive bootable installer.

Create the Yosemite install drive: The options
I’ve come up with three ways you can create a bootable OS X install drive for the Yosemite: using the installer’s built-in createinstallmedia tool; using Disk Utility; or performing the Disk Utility procedure using Terminal.

There is a free utility that will recreate the recovery partition.  (Backup Important)

But an easier approach is to use the free Recovery Partition Creator (more info here). This app can create the partition and even install the necessary OS X Recovery software on it. You just need to have a copy of your OS X installer—Mavericks, Mountain Lion, or Lion—on a connected drive.

It is really not that complicated. If you just go to the App store and re-download and re-install the operating system, the installer will automatically create a new recovery partition. You don't need a bootable external or any special software.
