I just listened to Lyla, guess three times or so, and i made some kind of a " quick-eared" list of the chords. It's very simple :

Artist : Oasis
songtitle : Lyla
by : "Shakermaker"

song played with capo on 2nd fret

intro: A

D/F/G/A
Calling all the stars to fall
And catch the silver sunlight in your hands
Call for me to set me free
Lift me up and take me where I stand

D/F/G/A
She believes in everything
And everyone and you and yours and mine

F/G/F/G/A
I waited for a thousand years
For you to come and blow me off my mind

A/G/D
Hey LYLA
The stars about to fall...
So what you say LYLA
The world around us makes me feel so
Small LYLA
If you can't hear me call
Then I can't say LYLA
Heaven help you catch me if I fall

(AND SO ON ...)

She's the queen of all I've seen
And every song and city far and near
Heaven help me mademoiselle
She rings the bell for all the world to hear

Hey Lyla
The stars about to fall
So what you say LYLA
The world around us makes me feel so
Small Lyla
If you can't hear me call
Then I can't say Lyla
Heaven help you catch me when I fall

somewhere in the song there is a kind of a BRIDGE,
guess it's played like this : EM/G (couple of times)
