House Tyrell traditionally held the title since the death of Mern Gardener and the extinction of his House during the War of Conquest, when Harlen Tyrell, the Steward of Highgarden, bent the knee to Aegon the Conqueror, but all prominent members of the house were killed after the Destruction of the Great Sept of Baelor and the Fall of Highgarden.
With the death of Randyll and Dickon Tarly and Daenerys reasserting her authority over the Reach, the position is currently hers to fill.

In the books
In the A Song of Ice and Fire novels, there is no mention of House Tyrell actually being granted the title of Lord Paramount. Instead, the title of "High Marshal of the Reach" seems to be the equivalent. This difference between House Tyrell and other Great Houses is never touched upon.
