Here is how to sign a transaction with an offline Electrum wallet.
1. With your online (seedless) wallet, create the transaction using mktx:
./electrum -w seedless_wallet mktx 1Cpf9zb5Rm5Z5qmmGezn6ERxFWvwuZ6UCx 0.1
{
"complete": false,
"hex": "01000000015a92850cc5dc7bb7c1a711c1ce0c1658596c085d49c17fce68c641cce0bdd188010000004801ff45fe197f1a7a7779f58690c3100364d7ce596bf47bb52e88e617e22940bf54a8f139194652584b0d357eb95defb8b4911b0a53118b8afecb96aedb1334e772df350901002800ffffffff02b1f0f65d000000001976a9147ea19cc36d846e2ce81762def3cb9299bed0847188ac80969800000000001976a91451e814c0f7637ba9a59bc11628337a2df6559a5088ac00000000"
}
Electrum returns an unsigned transaction. Note that the serialization
format contains the master public key needed and key derivation, used
by the offline wallet to sign the transaction.
2. Sign the transaction with your offline wallet: pass "hex" and "input_info" to 'signrawtransaction':
./electrum -w wallet_with_seed signrawtransaction 01000000015a92850cc5dc7bb7c1a711c1ce0c1658596c085d49c17fce68c641cce0bdd188010000004801ff45fe197f1a7a7779f58690c3100364d7ce596bf47bb52e88e617e22940bf54a8f139194652584b0d357eb95defb8b4911b0a53118b8afecb96aedb1334e772df350901002800ffffffff02b1f0f65d000000001976a9147ea19cc36d846e2ce81762def3cb9299bed0847188ac80969800000000001976a91451e814c0f7637ba9a59bc11628337a2df6559a5088ac00000000

}
The result is a fully signed transaction, as indicated by the "complete" field.
3. The transaction can be sent to the Bitcoin network with 'sendrawtransaction':
./electrum sendrawtransaction 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

./electrum mktx 1Cpf9zb5Rm5Z5qmmGezn6ERxFWvwuZ6UCx 0.1
{
"complete": false,

"input_info": "[{'scriptPubKey':'76a91411bbdc6e3a27c44644d83f783ca7df3bdc2778e688ac','electrumKeyID':(15,False),'vout':0,'txid':u'e7029df9ac8735b04e8e957d0ce73987b5c9c5e920ec4a445130cdeca654f096'},{'scriptPubKey':'76a914aaf437e25805f288141bfcdc27887ee5492bd13188ac','electrumKeyID':(112,True),'vout':0,'txid':u'b30edf57ca2a31560b5b6e8dfe567734eb9f7d3259bb334653276efe520735df'}]"
}
Note that returned json contains the unsigned tx in "hex". The field
"complete" is false because the transaction is not signed, and
"input_info" contains parameters that need to be passed to the offline
wallet so that it knows which private keys to generate.
2. Sign the transaction with your offline wallet: pass "hex" and "input_info" to 'signrawtransaction':
./electrum signrawtransaction 010000000296f054a6eccd3051444aec20e9c5c9b58739e70c7d958e4eb03587acf99d02e70000000000ffffffffdf350752fe6e27534633bb59327d9feb347756fe8d6e5b0b56312aca57df0eb30000000000ffffffff0280969800000000001976a91481acc8b7f9ec7cbf45a02dd8b758c6ac6a1481ca88acf4345c35000000001976a914aaf437e25805f288141bfcdc27887ee5492bd13188ac00000000 "[{'scriptPubKey':'76a91411bbdc6e3a27c44644d83f783ca7df3bdc2778e688ac','electrumKeyID':(15,False),'vout':0,'txid':u'e7029df9ac8735b04e8e957d0ce73987b5c9c5e920ec4a445130cdeca654f096'},{'scriptPubKey':'76a914aaf437e25805f288141bfcdc27887ee5492bd13188ac','electrumKeyID':(112,True),'vout':0,'txid':u'b30edf57ca2a31560b5b6e8dfe567734eb9f7d3259bb334653276efe520735df'}]"

}
The command returns a fully signed transaction, as indicated by the "complete" field.
This transaction can be sent to the network with 'sendrawtransaction'
