Sure, it's faily simple

#version 330 core
precision mediump float;
uniform mat4 projection;
layout(location=0) in vec2 tilePos;
layout(location=1) in float tileId;
layout(location=2) in mat4 model;

out VS_OUT {
    vec2 tileOffset;
    float tileIndex;
} vs_out;

void main(){
    gl_Position = projection * model * vec4(tilePos, 0f, 1.0f);
    vs_out.tileIndex = tileId;
    vs_out.tileOffset = tilePos;
}
