Is there the ".prj" file which contains the relevant "projection"
parameters?

Maybe you also need to "add" a projection to your vector map if the
".prj" file is missing (?). You can do that with the "-a_srs" parameter.

Take a look in the syntax (output of ogr2ogr): first you have to provide
a name for the *destination* and then the *source* filename. I think
your command should look like:
ogr2ogr -t_srs EPSG:32610 mynewfile.shp myfile.shp

This is a remark which should probably be directed to the author(?).
