First thing you need is a prompt trigger to capture your data. Let's pretend your prompt looks like this:
HP:456/890 MA:393/491 MV:12/930>
The trigger would look like this:
#TR {HP:(%d)/(%d) MA:(%d)/(%d) MV:(%d)/(%d)~>} {
#VAR hp %1
#VAR maxhp %2
#VAR mana %3
#VAR maxmana %4
#VAR moves %5
#VAR maxmoves %6
} "" "prompt"
Be sure to put the word "prompt" at he end of the trigger or check the "Trigger on Prompt" box in the trigger's settings editor.
Next, you'll need to build your gauges. Since I'm a lazy lazy man, I'm taking this one from the help files:
#GAUGE hpgauge "hp" @hp @maxhp (@maxhp/10) "" "blue" "red"
You can do gauges for mana and moves as well if you like.
