I'll see if I can build one.
There is a set of standard recipes, yes - Yocto has a reference distribution called Poky + there are additional layers with recipes such as meta-openembedded I'm using a lot.
Some of the packages I'm building are from the "standard set" for the current BSP's Yocto version (1.6), some I backported (or simply reused - the power of Yocto here) from the newest 1.7/1.8 (like Apache or MariaDB I've recently published) and some I;ve written from scratch (like Motion or fswebcam).
When you unpack the BSP (file with "-src-" in the name in Downloads section), you'll see the layers and "poky" dir - that's where the recipes are.
