You can use normalize to increase the volume of the encoded files:

There's no way to guarantee that VBR encoding won't fall below a certain 
level at some point.  I tried the same thing.  You'll have to use ABR:

oggenc --bitrate=104 --min-bitrate=96 --max-bitrate=224 whatever.wav

104 kbps is sort of -q 3.
