Smaug only appeared in the Hobbit, where he was killed and he never appeared again (because he was dead). So smaug was not in the Lord of the Rings trilogy, but he was in the Hobbit.

Smaug was drawn to the Lonely Mountain by the great riches stored there. Like all dragons, he had a great love for gold and precious stones.
The mountain where the dwarves use to live before smaug came and claimed the mountain and its gold.
