Welcome to Librarium Online!
Yay first post!
My friend is about to start 40k and I made him a small starting army with the Battleforce as a basis.
9 Dire Avengers 140p
10 Guardians 110p
Wave Serpent 110p
-Twin-Linked Shuriken cannons
War Walker 60p
-2 Scatter lasers
As I play Tau, my main concern is anti-tank fire. Can the lonely Bright lance drop a Hammerhead and a Devilfish before getting destroyed?
Well, for a 500 point game, anti-tank fire is not gonna be huge deal. The biggest thing you could be staring down will probably be a Leman Russ and the combined fire from the Bright Lance, Scatter Lasers and Shuriken Cannons will take it out. Go for rear or side armor!!! The War Walker and Wave Serpent can move up the sides and lay into them.
To answer your question, the lonely Bright Lance probably can't take a Hammerhead and a Devilfish alone. Guardians are just a poor shooting platform. However, shooting those strength 6 guns at rear or side armor will work wonders.

Personally, I think if that War Walker flanked, it could easily get a rear shot against your tanks. 8 Str shots, say 4 hit against AV 10, and you've likely got a dead tank on your hands.
Arvan'drynn Craftworld - 15,000pts (deceased)
Tau - 2,000 points (atomized while on patrol)
You also don't have much anti-tank firepower as you mentioned so you may want to look at putting a Brightlance on this as well as with the Guardian Defenders if you can find the points.
Hope that helps.
For maximum efficiency, I would switch the TL Shuricannon on the Serpent for a TL Bright Lance, and then downgrade the guardians Bright lance to a shuricannon or scatter laser.
If this requires dropping the Stones from the serpent or making the scatter lasers shuricannons on the walker, I think it'd be worth it.
And I agree the doomseer with the avengers in the serpent is pretty much your cash unit so that should fare well.
Thanks for all the comments! We pretty much redid the list yesterday.
10 Dire Avengers 152p
-Twin Catapults, Bladestorm
Wave Serpent 145p
-Twin-Linked Bright Lances
5 Pathfinders 120p
As you can see, the War Walker and Guardians got swapped for Pathfinders and Bright Lances for the Wave Serpent.
Does this look better than the first list?
The second list is pretty solid, I think it'd do quite well against Tau. I'd be tempted to try and stick a D-Cannon Support Weapon Team in there, maybe downgrading the Bright Lances to Missile Launchers and the Pathfinders to Rangers. D-Cannons are fun!
