Rovers beat Dagenham & Redbridge in the first ever Conference play-off final to earn a return to league football.
52-year-old Ryan made history in April when he made his playing debut for Rovers as a late substitute in the 4-2 win over Hereford United.
He said: "We're not there to make up the numbers next season.
"The target is to win Division three. We've got to have the right ambition."
