Pitfall traps are your best friend there. The gunlance's shelling may be able to nail it as well if you use the upward strike, not sure though, haven't tried that out. I play online a lot, and usually I have the awesome benefit of a hammer user knocking him senseless, or bow users putting him to sleep. The part breaker skill can also be helpful here, as Lagiacrus' back in general seems a LOT harder to break now.
