It's a bit more than "a bit of flavor" (and Tracy Hickman has been quite forthcoming on this stuff)
The disks of Mishakal are direct analogs to the golden plates.
The fall of the church of Istar represents the Mormon view of the Catholic Church (the turning of man from god, and god waiting to be found again).
Knowledge of the Real God being revived by a Native American (Goldmoon), just like in the Book of Mormon's revelations.
Elistan is a thinly-veiled Joseph Smith stand-in. Paladine is Mormon Jesus.
Goldmoon uses the Pearl of Great Price gem analogy.
The Cataclysm is the Great Apostasy.
The High Council is, well, the High Council.
Oh, here, this post explains it better than I can:
Dragonlance based on Mormonism?!?
It's not accurate to say that there's a bit of Mormon flavor in Dragonlance. Mormon theology is the backbone of the original novels.
I'm not saying that's good or bad, but's it's inarguably there (and yes, it is portrayed as "The Way" and upheld by the heroes). And I'm not saying that Dragonlance is Mormon propoganda in that way that Narnia is Catholic propoganda (Dragonlance certainly never directly proselytizes in favor of actual real-world Mormonism the way the Narnia books do for Catholicism).
And to be very clear, I'm certainly not passing any positive or negative judgment on Mormonism beyond saying that it is a HUGE factor thematically in Dragonlance.
And I do think that in today's atmosphere there's potential for trouble there if it's not handled very carefully.
