Skipuleggja is the infinitive form (the dictionary form: to plan / to organize).
In the sentence you need a conjugated verb that matches the subject við (we), so you use the present tense, 1st person plural:
- ég skipulegg – I plan
- þú skipuleggur – you (sg.) plan
- hann / hún / það skipuleggur – he / she / it plans
- við skipuleggjum – we plan
- þið skipuleggjið – you (pl.) plan
- þeir / þær / þau skipuleggja – they plan
So við skipuleggjum literally means we plan / we are planning.
