HERE IS YOUR ANSWER

Veda is Karma Kaand, But Bhgvad Gita is the final essence of human Life. As Sri Prabhu-Ksb mentioned in his answer, Vedas are the main authority. They too came from the same source, God. They were more exhaustive and contain a very vast range of information in the form of hymns, rituals etc..
