Should we give them the Law subtype, like their vaati masters?
Combat: A hound’s keen senses give it a +1 bonus to its own surprise rolls and allow it to detect invisible creatures 50% of the time.
Racial bonus on Listen and Spot checks? Blindsense?
A hound of law can move to the Astral or Etheral plane or become invisible at will. A hound on the Ethereal or Astral plane can materialize and attack creatures on the Prime Material Plane, imposing a -5 penalty on opponents’ surprise rolls.
Simplify to ethereal jaunt, like the ethereal marauder?
Hounds of law are unaffected by spells except protection from evil (good), magic missile, and maze.
Immunity to Magic (Ex): A hound of law is immune to most spells or spell-like abilities that allow spell resistance, except magic missile, maze, and those with the chaotic descriptor.
Hounds of law gain a +1 attack bonus when fighting chaotic creatures, and chaotic creatures suffer a -1 attack penalty and a -1 penalty to each die of damage inflicted (minimum one point per die).
Should this only apply to creatures with the Chaotic subtype, or all chaotic-aligned creatures?
Edit: It appears that the vaati in 3e have air mastery.
A hound can track creatures by sight and scent; use the tracking proficiency. The hound’s base tracking score is 16, and it ignores vision-based penalties (such as poor lighting or attempts to cover tracks).
If a creature a hound is tracking uses flight or teleportation magic of any kind, the hound can use residual magic energies to automatically follow the creature. To determine success, make a tracking roll at a -2 penalty; adjustments for the trail’s age apply, but other adjustments do not. If the roll fails, the hound cannot follow the creature. If the creature the hound is following died or was entrapped in a solid object or on another plane as a result of a teleport, a hound that has made a successful tracking roll senses the disaster and need not follow. When following a teleporting creature, a hound can carry 250 pounds of additional weight.
Track as a bonus feat?
Modify this...
Astral Tracking (Su): A spectral hound can attempt to track normally even through the featureless wastes of the Astral Plane (base DC 25). A spectral hound can use this ability to track quarry that uses a teleportation spell to travel, by entering the Astral Plane at the departure point, following the trail of the teleportation through the Atral Plane, and returning to the plane of departure at its quarry's destination.

Planar Tracker [General]
You can track a creature through the magical signature it leaves behind after using a teleport or plane shift effect.
Prerequisites: Alertness, Track, Wilderness Lore 15 ranks.
Benefit: Using the Track feat, you can follow tracks even if your quarry has used a teleport or plane shift effect to escape. When you reach the location at which the magical method of escape was employed, you can attempt a Wilderness Lore check (DC 30). Success means you are aware that a teleport or plane shift effect has been used. If your check result beats the DC by 10 or more, you konw which effect was used. If your check result beats the DC by 15 or more, you know the firection in which your quarry has moved (in the case of teleportation) or the destination plane (in the case of plane shift). In any case, if you locate the creature's tracks within 1 hour per character level, you can instantly identify them as your quarry's and attempt another Wilderness Lore check (DCs as given in the Wilderness Lore skill description in the Player's Handbook) to determine how fresh they are.
