What methods could this alien race use to terraform the Earth so it resembles their homeworld?

Some information about their homeworld:

• Their homeworld, 0.34247 (M⊕) 0.54 G, 10156 km.

The atmospheric pressure of their homeworld is 62% of the Earth's, and the planet has an average temperature of 87.6 kelvin. The atmosphere consists mainly of

• 68.1% Nitrogen

• 28.6% Methane

• 1.71% Carbon dioxide

This is for a story I'm in the process of writing. An alien race from a planet that resembles Titan wants to colonize Earth and terraform it to make it resemble their planet. They are 3ft in height and weigh 60-80 pounds on their own planet. They are also extremely advanced - at least 1000 years ahead of humanity in technology, such as medicine and space travel.
