I don't think you can directly use the same commandline options in gst
pipelines. I found this reference for the lame encoder:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-ugly-plugins/html/gst-plugins-ugly-plugins-lame.html

Based on the examples in the link I sent before, I was under the
impression that mode=0 specificed VBR (variable bit rate) and mode=1
specified CBR (constant bit rate) but looking at this latest link, I
am not so sure now since it specifies "Stereo" as the default.

You might have more success with just using one of the presets. Remove
all the mode/vbr-quality/bitrate stuff and just put in preset=extreme
for very good encoding (VBR at target bitrate of 245 kbps) or
preset=insane (CBR at 320 kbps) for the best you can get. You will get
big files with either of these. Both preset=standard (VBR at target
bitrate of 190 kbps) and preset=medium (VBR at target bitrate of 165
kbps) will give you a lot better than CBR at 128 kbps.
