The gdal_translate utility has the switch '-b' to specify the bands. For
example, if you want to convert the first and the third bands from the
input image you can do the following:

 $ gdal_translate -b 1 -b 3 input.tif output.tif

So you should run gdalinfo on your HDF file first, select the subdataset
to convert and run the gdal_translate on that subdataset specifying the
band(s) you want to extract.
