There is nothing inherent to Mathematica to make it run as a background process. This is the operating system's job. So, the question you need to ask is, "how would I make *any* program run as a background process?".
The run argument has nothing to do with the background process...it simply instructs Mathematica what to do when it first starts up. Thus, you could pass it a command through run which tells it to run a package. If you want Mathematica to quit gracefully at the end, then you'd put a Quit[] command at the end of your package.
On a Unixbased system, you could run Mathematica in the background by simply attaching an & after your commandline. For example:
math < infile > outfile &
(note that in Unix, you can also use redirection as I did for input and output files...I find that somewhat easier to remember than the run argument).
