How do I get rep for the Shado-Pan without having the Tabard?
Once you're Reverd with Golden Lotus*, head over to their daily quest hub in Townlog Steppes to pick up dailies for rep.
You also have the option to click the star next to "Shado-Pan" in your rep tab which will allow you to "champion" them. For your first Heroic Dungeon and Scenario of the day, you'll get 300 and 200 rep respectively with whatever faction you're championing, without needing to do dailies or get rep with Golden Lotus.
And finally, once you're Revered with the Tillers, you get the option to buy the farm which opens up Work Orders to gain rep with different factions. Completing a Work Order for the Shado-pan will give you 400 rep. At present you will need to unlock the Shado-Pan dailies by hitting revered with Golden Lotus to start Work Orders for them.
*In patch 5.3, the rep requirement with Golden Lotus is being removed from the Shado-Pan and August Celestials dailies, but for now you'll need to get that first.
