Take a look at spells. make options to trade out action surge, extra attack and indomitable for things that are martial and non magical but on par with spells. if you trade at level 12 use a 6th level spell... if you trade at level 5 look at 3rd level spells.
off the top of my head "Leap before you look" once per day as an action you move up to twice your movement, then where you would stop make a melee attack against all enemies within a 20ft radius. Each attack that hits deals double damage, and each one that misses deals damage equal to your attack stat modifier. that isn't a fireball but it is pretty close
"Leap of the Leaper" once per day as an action you grant yourself the ability to tipple your jump distance. This lasts for up to 10 minutes* concentration. this isn't jump but it kinda is
I would prefer a full blown warlord class but that is a great starting point.
