(MO > LLL, qepHom 2017, p.14, WRT "bait" in DSC subtitles):  I think you can use either tlhu'moH "tempt" or ngel "attract, lure".  In either case, I suspect you'd use the -meH suffix. It would be something like "...use a spaceship in order to lure/attract/tempt them."  ngelwI' would be an attracter or a lurer, so that could be the noun "bait" in this context.

Here's the finished non-canon subtitle:

pa'vovo' chaH DIngelmeH, 'oH wIlo'.
We use it as bait, to draw their flagship away from Pahvo.
(DSC/sub "Into the Forest I Go")

(Felix, 11/13/2017):  Appears to mean something like lure, bait, attract, divert or draw (toward / away from). Interestingly, it's leng backwards, which might give some hint as to its meaning.
