 * Lucy's with Wendy, who's also a Dragon Slayer and thus should have just as good senses as Natsu and Gajeel.
 * Gajeel's team has a lacrima, so if Lucy takes the one they are using with them, Gajeel's team can give them directions.
 * With Erza, Mirajane and Natsu all being at the place, Cana might be able to divine their location and direct the other teams there via lacrima.
 * They could all meet up at the chairmans house and track Natsu from there.

I think the tracking is really the smallest problem now that Natsu has already found his was to Tartarus HQ.
