SELECT OBJECTPROPERTY(OBJECT_ID('MyTable'), 'TableHasIdentity');

-- when using an API wrapper, one can reduce the entire check to just checking for rows. For instance when using C#'s SqlDataReaders property HasRows and a query construct like:
SELECT CASE OBJECTPROPERTY(OBJECT_ID('MyTable'), 'TableHasIdentity') WHEN 1 THEN '1' ELSE NULL END

-- more flexibility but needs column name
SELECT * FROM sys.columns WHERE object_id = OBJECT_ID('MyTable', 'U') AND name = 'MyTableIdentityColumnName';
