Irish mobile phones begin with 083 or 085 or 086 or 087. To dial any of those four you would dial: 00 353 and then leave out the first zero and dial the other two digits. So if you were dialling 085 9999 999 you would dial:
00 353 85 9999 999.
Best way: replace the trunk prefix 0 of the English number with country code +44. Dial the full international number, beginning with the plus sign.
Alternative: replace the trunk prefix 0 with 00 44.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)
To call a UK mobile from a landline in Ireland, dial:

44 = country code for the UK
7XXX = mobile code, omitting the leading 0
(6-digit mobile number)

Dial the Irish mobile number exactly the same way that you would if it were in Ireland.
Just dial the UK mobile number. It does not matter that the mobile is roaming in Ireland (or anywhere else); the network will automatically locate the mobile, and the roaming mobile user will pay any applicable roaming surcharges.
Just as you would call an English landline.
To call a UK mobile from a UK landline, you always just dial the UK mobile number, exactly the same way you do when it is in the UK. The network will find the mobile automatically, and the mobile user will pay any applicable surcharges for international roaming.
