According to 2000 Census, 3.6% of all Americans are Asian-American, and only 2.2% of all American lawyers are Asian-American. Both cite their sources as the 2000 U.S. Census (and the lawyers # is from the ABA. Couldn't find the number specifically for Indians, but I imagine it's somewhat proportional to the rest of the Asian population. Indians make up 1% of the American population, and I imagine they make up less than that of the American lawyers population.
So, while Indians are not nearly as underrepresented as Blacks or Hispanics in law, they're certainly not an ORM and Asians ought to stop being treated as such.
